Abstract or Summary

The Green Lacewing, Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae) is a successful predatory insect; augmented for bio control practices especially for Integrated Pest Management. It is observed that green lacewing C. carnea (Steph.) has good potential of predation and caught good attention for its successful use against sucking insect pests. Currently it was evaluated for the management of white fly Bemisia tabaci infesting cotton crop. The data shown that the predator reduced white fly B. tabaci population significantly. Overall maximum population reduction was recorded in T-1 Chemical Control (6.01±3.75/leaf) followed by T-2 Bio-Control (green lacewing C. carnea) (6.84±3.90/leaf) as compare with control (8.50±4.93/leaf) While maximum population of Whitefly B. tabaci (10.40±5.75/leaf) recorded in non Bt. Control (NIAB-78). Acetamaprid 20SL has good toxicity recoded minimum predatory population (0.04/plant) in T-1 (Chemical Control plot); maximum were observed (0.3/plant) in T2 Bio-Control (Green Lacewing C. carnea) released plot.
